詳情介紹
物料切斷閥是我公司引進美國ITT Engineered的技術，開發研制的新一代產品。廣泛應用于建材、冶金、礦山、石油、化工、玻璃等行業的管道或氣力輸送系統中，作切斷或調節用。
This valve is the new designed product importing new technology of American company ITT Engineered. It is used to cut off or adjust valve, which is applied in pipe or pneumatic transportation system in building material, metallurgy, mining, oil, chemical and glass industries etc
結構特點：
Structure characteristic:
物料切斷閥采用優質鋼材焊接而成，其結構科學合理，緊湊獨特，操作靈活，維護方便，密封性能可靠。其楔緊工作原理使插板越關越緊，使密封永遠處于良好狀態。而插板一旦開啟，馬上與密封面脫離，以保證密封面不受磨損，且密封面敞開式，物料無法附著和沉積。此構造是密封的關鍵所在。W表示密封面為橡膠軟密封，P表示密封面為合金硬密封。配用不同的傳動裝置滿足不同工況需求。Z73為手輪傳動，WZ73為蝸輪傳動，DZ73為電動裝置傳動，QZ73為氣動裝置傳動。
The valve is welded in fine steel, having the features of compact and scientific structure, hand to operate, easy to maintenance and reliable sealing. The working principle is choking, the sealing is always in the best state while the disc is closed. The disc separates from sealing surface when it is opened, which avoids abrasion of the sealing surface. The sealing surface is in open state and the material cannot cohere or deposit, which the key to the sealing. W means the sealing surface is rubber soft sealing, P means the sealing surface is alloy hard sealing. It can meet different requirement of working conditions equipped with different transmission devices. Z73 denotes hand wheel drive, WZ73 denotes worm gear drive, DZ73 denotes electric device drive and QZ73 pneumatic device drive.

工作原理：
Working principle
物料切斷閥主要由閥體、插板、密封副、傳動桿及傳動裝置等部件組成。手動物料切斷閥由人工轉動手輪，沿順時針方向為關，逆時針方向為開。由旋轉螺母帶動傳動桿作向上運動，使插板脫離密封面向上位移，直至全開，反之為關。蝸輪傳動物料切斷閥由人工轉動蝸輪裝置手輪，順時針方向為關，逆時針方向為開，帶動蝸輪副旋轉從而帶動傳動桿向上運動，使插板全開，反之全關。電動物料切斷閥由Z型電動裝置得到指令動作旋轉螺母帶動傳動桿作運動，使插板起到開關作用。氣動物料切斷閥由二位五通電磁換向閥控制，10A-5R氣動推桿帶動傳動桿作往復運動，使插板起到開關作用。
The valve is mainly made up of body, inserting disc, sealing pairs, transmission pole and transmission device etc. The hand wheel of the manual valve is rotated in clockwise and closes the valve, anticlockwise rotation means open. The transmission pole moves upwards and makes the disc separate from sealing surface and move upwards until the valve is fully opened. The hand wheel of worm gear drive valve is rotated by hand. Clockwise rotation means close and anticlockwise means open. The transmission pole moves upward, the worm gear pairs rotate until the disc is fully opened. Type Z electric device of electric valve receives the order and rotates nut to drive the transmission pole in order to open or close the disc. The pneumatic valve is controlled by two-bite five-way electromagnetism reversal valve. Type 10A-5R pneumatic draw stem drives the transmission pole move reciprocally to open or close the disc.
